kotlinlang

I have a common function written in kotlin which returns a ByteArray, and I'd like to use this on iOS. I though that ByteArray should be a Data on iOS, but it seems like it's a KotlinByteArray. Any way to convert it to a Data? Or something else that is "recognized" by swift?

probably performances aren't that great, but right now on kotlin side I'm using `myByteArray.toList()` in order to return a List&lt;Byte&gt; to the swift side, then on swift I'm casting every KotlinByte to a Int8 (`myKotlinByte as! Int8`) then every Int8 to UInt8 (`UInt8(bitPattern: myInt8)`) and finally merged every UInt8 to an array and pushed it to a Data object

Looks like a lot of work to me! Why not just push it byte by byte to NSMutableData?

Just checked what I’m doing in my case:

```
    NSArray&lt;KotlinUByte *&gt; *encodedRecord = [self encode];
    NSUInteger byteCount = encodedRecord.count;
    unsigned char *buffer = malloc(byteCount);
    for (NSUInteger i = 0; i &lt; byteCount; i++)
        buffer[i] = [encodedRecord[i] unsignedCharValue];
    return [NSData dataWithBytesNoCopy:buffer length:byteCount];
```
Hope that helps.
